Time has not healed the political wounds of the 2010 BP oil spill in the Gulf of Mexico.

Speaking yesterday at the Conservative Political Action Conference, Louisiana Gov. Bobby Jindal said Obama administration officials “wasted precious time while that oil was coming in to our coast.”

Jindal, a Republican who has been one of the most persistent critic of President Obama on issues ranging from energy to health care, intensified his two-year-old critique of the White House’s response to the massive oil spill that followed the explosion of the Deepwater Horizon off the coast of Louisiana.

“They refused to listen to the people who lived along the coast that knew better than all the experts,” Jindal told the largest annual gathering of conservative activists, as reported by NBC’s Jamie Novogrod “What I saw and what I heard were people that were maybe very, very book smart, but had never run anything in the private sector.”

In his attacks on Obama, Jindal mocked the president for boasting about the bona fides of Energy Secretary Steven Chu.

“During our regular meetings and calls, the president would talk regularly about his ‘Nobel Prize-winning energy secretary,’ ” Jindal said. “I’d begin to think that was part of his title.”

Chu, a University of California-Berkeley physicist, won the Nobel Prize for Physics in 1997.
